I find Mr DD loves that right handed tomohawk. I can make him go left as a defender --- he must practice his left hand tomohawk.

If anything that video pointed out that he was going to his left off the dribble or spin every time... He doesn't need to practice tomahawks or any dunks for that matter - he needs to practice breaking down his man off the dribble so he can get close enough to the rim to use his fade-away/force a double-team/drop step + bank-shot/etc. As of right now the only dunks in his repertoire is off the fast break and finishing a lob-pass.... His fundamentals are where he needs work but these various videos of his work during the summer shows that he's expanded some of that...
